Abstract
In this work, novel metal oxide-organic frameworks (cellulose nanocrystals (CNCs)), copper oxide/melamine/cellulose nanocrystals (CuO@MEL@CNCs), and nickel oxide/melamine/cellulose nanocrystals (NiO@MEL@CNCs) were effectively fabricated using a hydrothermal method. The prepared nanocomposite CNCs, CuO@MEL@CNCs, and NiO@MEL@CNCs were described by Fourier transform infrared (FT-IR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), and Raman spectroscopy. The outcomes show that the nanomaterials have high scattering and narrow size distribution. Moreover, vibrational investigations have been performed utilizing Raman spectroscopic procedures. Explicit Raman peaks were observed in the CNC, CuO@MEL@CNC, and NiO@MEL@CNC nanostructures, and the full width at half maximum (FWHM) of the peaks demonstrated the small particle size of the prepared nanocomposites. The capability of the CNC, CuO@MEL@CNC, and NiO@MEL@CNC nanocomposites to act as corrosion inhibitors of AISI360steel in molar H2SO4 is described for the first time. The corrosion protection capabilities of the nanocomposites were evaluated using potentiodynamic polarization (PDP), impedance spectroscopy (EIS), and surface morphology (FE-SEM/ energy dispersive X-Ray analysis (EDX)) measurements. The protection effectiveness was found in the order NiO@MEL@CNCs (98.3%) > CuO@MEL@CNCs (96.8%) > CNCs (85.3%) at 300 mg L-1. The current report shows that CNCs and metal oxide-melamine frameworks at CNCs as inexpensive and eco-friendly inhibitors could be probable candidates to protect AISI360-steel corrosion in petroleum manufacturing.
